1. A client with atrial fibrillation is prescribed warfarin (Coumadin). The nurse should reinforce which dietary instruction?
- A. Avoid foods high in vitamin K.
- B. Increase intake of dairy products.
- C. Limit intake of foods high in fiber.
- D. Increase protein intake.
Correct answer: A
Rationale: The correct answer is to avoid foods high in vitamin K. Clients taking warfarin (Coumadin) should maintain a consistent intake of vitamin K to keep the medication's effectiveness stable. Foods high in vitamin K, such as leafy greens, can interfere with the anticoagulant effects of warfarin. Therefore, it is crucial for clients to avoid these foods to ensure the therapeutic effects of warfarin. Choices B, C, and D are incorrect because increasing dairy products, limiting fiber intake, or increasing protein intake do not directly impact the effectiveness of warfarin therapy and are not necessary dietary modifications for clients on this medication.
2. The client at risk for thrombophlebitis receives reinforcement from the LPN/LVN regarding measures to minimize its occurrence. Which statement by the client indicates an understanding of this information?
- A. I should avoid sitting for prolonged periods.
- B. I will take frequent walks and avoid prolonged bed rest.
- C. I should drink plenty of fluids to stay hydrated.
- D. I will use compression stockings as advised by my doctor.
Correct answer: B
Rationale: The correct answer is B. Taking frequent walks and avoiding prolonged bed rest are essential measures to promote circulation and reduce the risk of thrombophlebitis. Physical activity helps prevent blood from pooling and clotting in the veins, thus decreasing the likelihood of thrombophlebitis development. Choice A is incorrect because while avoiding prolonged sitting is important, it is not as effective as engaging in physical activity. Choice C is not directly related to preventing thrombophlebitis. Choice D, using compression stockings, is a helpful measure but not as effective as regular physical activity in preventing thrombophlebitis.
3. A client receives discharge teaching for a new prescription of lithium. Which instruction should be included?
- A. Take the medication with food.
- B. Increase your intake of sodium.
- C. Monitor for signs of hypercalcemia.
- D. Avoid consuming dairy products.
Correct answer: B
Rationale: The correct instruction to include when a client receives discharge teaching for a new prescription of lithium is to increase their intake of sodium. Lithium can lead to decreased sodium levels, putting the individual at risk of developing hyponatremia. By increasing sodium intake, the client can counteract this risk, maintain a proper sodium balance, and prevent complications. Choices A, C, and D are incorrect because taking lithium with food, monitoring for signs of hypercalcemia, and avoiding dairy products are not directly related to managing the side effects or risks associated with lithium therapy.
4. A client with a history of angina pectoris reports chest pain while ambulating in the corridor. What should the nurse do first?
- A. Check the client's vital signs.
- B. Assist the client to sit or lie down.
- C. Administer sublingual nitroglycerin.
- D. Apply nasal oxygen at a rate of 2 L/min.
Correct answer: B
Rationale: When a client with a history of angina pectoris experiences chest pain while ambulating, the priority action for the nurse is to assist the client to sit or lie down. This helps reduce the demand on the heart by decreasing physical exertion. Checking vital signs, administering medication, or applying oxygen can follow once the client is in a more comfortable position. Checking vital signs (Choice A) may be important but addressing the immediate discomfort by positioning the client comfortably takes precedence. Administering sublingual nitroglycerin (Choice C) is appropriate but should come after ensuring the client's comfort. Applying nasal oxygen (Choice D) can be beneficial, but it should not be the first action; assisting the client to sit or lie down is the initial priority.
5. When providing teaching to a client with a new prescription for atorvastatin, which of the following instructions should the nurse include?
- A. Take the medication in the evening.
- B. Take the medication with food.
- C. Increase your intake of grapefruit juice.
- D. Avoid consuming dairy products.
Correct answer: A
Rationale: The correct instruction for a client with a new prescription for atorvastatin is to take the medication in the evening. Atorvastatin is more effective when taken at night because cholesterol synthesis is higher during this time. This timing helps optimize the drug's cholesterol-lowering effects and enhances its overall efficacy in managing lipid levels. Choices B, C, and D are incorrect. Taking atorvastatin with food can decrease its absorption, grapefruit juice can interact with atorvastatin leading to increased side effects, and there is no specific need to avoid dairy products while on atorvastatin unless instructed otherwise by the healthcare provider.
